Hey Guys, i have a high milage sr20det (250k + miles). Its currently bone stock and drives well.

I am not trying to make any type of ridiculous power. Think ~300hp s15 turbo build. MY question for the brain trust, before swapping the turbo and upping the boost a little, should I refresh the motor / rebuild the head or can a motor of this milage take the extra power.

Fwiw, its a babied street car that gets driven literally as a grocery getter and on the weekends.

Apologies for the elementary question, but appreciate the responses
